(cAAC) afforded the acyclic silanylidene and germanylidene anions in the form of potassium salt [K(cAAC)MTip]2 (M=Si (1); Ge (2)). The silanylidene and germanylidene anions are valence‐isoelectronic to the well‐studied phosphinidene and are a new class of acyclic anions of Group 14. Compounds 1 and 2 were isolated and well characterized by NMR and single‐crystal X‐ray structure analysis. Furthermore, the

New hydro-, halo- and hydrohalogermanes of the types IsGeH(3-n)Cl(n) (n = 0, 1, 3, Is = 2,4,6-triisopropylphenyl) and Is(R)GeH2-nXn (n = 0 or 2, X = Cl, F), potential precursors of stable, low-coordinated species of germanium, have been synthesized. All of them are substituted by at least one bulky 2,4,6-triisopropylphenyl group, R being a second Is group, a mesityl, a pentamethylcyclopentadienyl or a fluorenyl group.
